FIRE-ESCAPE.

SPECIFICATION, forming Vpart of Letters Patent No. 294,629, dated March 4, 1884.

I Applicaiion filed May 19, 1883. (No model.)

rope in full located through the hollow center 5 Fig. 2, aside elevation of the upper end; Fig.' 3, a cross-section on the dotted line in Fig. l; Fig. 4L, a rope-gripper in perspective; and Fig. 5, same, showing the other side. 1

The tubular stock P is threaded around its lower portion, Fig. I, and slotted in two opposite sides ofthe upper portion. A crown, A, is screwed on the top and secured with a setscrew. Loops L L are connected with the crown, with which loops the body-belt (not here shown) is to be connected. Rope-grippers E are made asin Figs. 4 and 5, having semi-cyl- The bevel of these grooves is on an angle cor- I responding to that of the flange a.- The compressing-cylinder B is operated by a handtube, D, coupled with its lower end by means of a threaded collar, c, screwed onto` theend of said cylinder B. The collar c has an inter! nal iange at its lower edge located under an external flange, c, of thehand-tube D, by which means the hand-tube is free to turn and carries the cylinder B up and down. The hand-tube is threaded internally throughout its length, and Screws onto the threaded portion of the stock P. Athimble, o, is inserted in the upper end of the stock P, which prevents the parts of said stock from becoming'compressed,

and thus encroaching upon the desired width 4of the slots and binding the Iianges a a of the grippers E. This thimble o, being perforated to the size of the rope used, serves to accurately center said rope in the device.

In the operation, the operator runs the cylinder Bup the stock by turning the hand-tube portions ff ofthe grippers E. After securing the body-belt about the waist `and throwing the weight of the person on the device, which holds said person suspended, the operator, with his hand all the time on the hand-tube D, gently turns the same, lowering the cylinder B, which releases the rope from the grippers E and allows the operator to descend. The rate at which the operator goes down the rope is" readily controlled; or, if desired, he can stop at any point by again compressingthe grippers. The parts, being thus threaded and screwed together, are all detachable from each other.

Having thus described my invention,what I claim is- 1. In a fire-escape, the combination, with the tubular stock having the slots and the grippers loosely located'therein, of a vertical- Vly-playing v'compressing-cylinder and means for operating it, substantially as set forth.

- 2. The combination of the semi-cylindrical grippers having the beveled iiange, a tubular stock, and means for compressing said grippers, substantially as described and shown.

3. The stock provided with the crown, having the belt-loops, in combination with the grip` pers, the compressing-cylinder, and the handtube, substantially as specied and shown.

4. In a lire-escape, the combination of the slotted tubular stock having the lower portion threaded, the semi-cylindrical grippers having the beveled iiange, the compressing-A IOO YStock, the internal thi1nb1o,tho grippers 11m'- In testimony ofthe foregoing I have herounto subscribed my naine in the presence of I3 two witnesses.
